8.22: Tropical Moist Climates

Whether a place is wet all year round or dry for some time really affects what can grow there. In the tropics, places that are wet year round have lush vegetation. Places that are dry some of the time are much less lush.

Tropical Climates

Tropical climates are found around the equator. As you'd expect, these climates have warm temperatures year round. The warm air rises at the equator. As it rises it cools, causing it to rain. Tropical climates may be very wet, or wet and dry.

Tropical Wet Climate

Tropical wet climates occur at or very near the equator. They have high rainfall year round.
Tropical rainforests
grow in this type of climate.

A tropical rainforest in Malaysia, Asia.

Tropical Wet and Dry Climate

Tropical wet and dry climates occur between 5° and 20° latitude and receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season, so the main plants are grasses (see
Figure
below
). Wildlife thrive on these grasslands.

Africa is famous for its grasslands and their wildlife.

Vocabulary

tropical rainforest
: A forest that grows in a tropical wet climate with high rainfall year round.

Summary

Tropical climates are found at or near the equator. Because warm air rises at the equator, there is a lot of rain.
